Context & Register
语域：formal 常见场景：正式写作、学术或法律文本 obviate 通常用于正式语境，多出现在学术、法律或书面表达中；日常口语里更常使用 avoid 或 make unnecessary。
Pronunciation & Spelling
注意：obviate 重音在第一个音节，读作 /ˈɒbvi.eɪt/。上面这些词都以 -iate 结尾，但读音并不完全相同：deviate、alleviate、abbreviate 的结尾都是 /vi.eɪt/，与 obviate 的结尾相同，但因重音元音不同，它们并不真正押韵，仅适合拼写对照；appropriate 作形容词时结尾 -ate 发 /ət/，不是 /eɪt/，不要被拼写误导。
